AIF and optimizing proppant distribution.
Doing so will mean overcoming numerous
complexities and hurdles, which will take
time. Fortunately, the modeling studies
also show that even modest gains in uniformity,
such as the ones from ongoing
improvements to limited entry designs,
can create significant value.
